Geli,
Thank you much for taking time to look at the drawing to shed some more light. Its starting to come together.
The sketch you posted is very much like the plans that I have. Perhaps the book you found it in used the same plans. Room #5 (with the question mark) does not exist. Room #1 is the end.
I take it your plans also show just unlabeled rooms for the three #4 on the right hand lower side? (Antikoeper's suggestion it is where the staff lived seems likely).
No, the dining room is #4 and #5 on the left.
The # 4 part of the Dining Room has a wall between it and the bedroom (#1) I guess? Is there any walls between # 4 and # 5, or is the Dining Room all one vast long space directly adjoining the study (#6).
My plans include diagrams of furniture, and it looks like one rounded section was a sitting room and the other had a desk.
Is it the left or right rounded section (in the drawing) that contains the desk? Was I correct that the library is #7?
The ones on that link are very nice
On that site, is that the main central staircase you think, or the back one?
(Regarding the back side of the complex)
Yes, I have. I was looking at my photos the other day, trying to match up the windows.
Ah, good. From the following, it seems you already had the idea of the brochure or pamphlet. Excellent.
(You are right about the Lee Miller photos --- I wonder if those on Geoff's site are all those that were in the issue of that May 1945 LIfe magazine. I am going to see if I can go look at a full copy in the library - hopefully intact pages -- and report to the thread. I know the 1945 volumes are there.)
I took a lot of photos; I was thinking of making a brochure or booklet. But it's a lot of work. I would want to add other people's photos as well. The ones on that link are very nice and would work well with the photos that I took to give an overall sense of the apartment. And such a brochure would need Lee Miller's photos and some other photos from the time period.
I would strongly encourage such --- not because of some expectation or market demand (though I do indeed think it would sell), but because you have clearly dedicated great interest and study to this setting and Geli's story. That kind of loving gathering of odd bits of data and photographs and putting them together naturally earns an expression. Though often growing slowly over years. Add that to the actual chance to visit, and it just seems to me it kind of is `asking' you to.

That is how such muse ventures often work. My two cents.
